LOCKING MEANS FOR DOORS.

Application filed November 25, 1921.; Serial No. 517,438.

To all it may 009mm:

Be it known that I HENRY C. Tnos'r, a

' citizen of the United tates, and a resident of El Paso, in the county of El Paso and State of Texas, have invented certain new and useful Improvements in Looking Means for" Doors, of which the following is a description, reference being had tothe accompanying drawings, which form a part of my specification.

My inventionrelates to means more especially intended for locking and controlroom, upon entering the same from his room or'compartment, may so adjust the means that the door leading from the oppositevroom will be locked to prevent the occupant of said room from entering the bath room while in use.

Another object of my invention is to provide means which will be simple in construction and application and at the same time easy of operation, whereby the simultaneous locking of the opposite doors leadin from .bothcompartments is accompllshed and at the same time locking" of the outer door leadingfrom the occupants compartment will be made impossible from the compartment-side thereof while the individual is in the bath room. 1

' -The invention and its advantages will be more readily comprehended from the detailed description of the v drawings, wherein 1 I Figure 1 is a sectional plan view of a bath room and portions of two adj ac'ent compart ments, illustrating the application of my improved locking means.

Figure 2 is a detail view, in perspective, of a portion of one end of the bath room with my improved locking means.

Figure 3 is a detailview, partiall in section, illustrating. the position of t eflopking means as shown at the right inFigure 2.

Figure 4 is a detail view, partiallyin' section, illustrating the position of the means as indicated at the left in Figure 2.

Figure 5 is a detail view, in elevation,

of the modification of my invention shown 1 at the left hand end of Figure 1. I

Figure 6 is aesectional view of the construction shown in Figure 5. a i

In the exemplification of the invention'as drawings, the invention is shown ap lied to chambers or compartments dispose between two rooms; theone chamber repre-. senting a bath room while the other chamber represents a toilet, both of which are accessibleby separate doors from the adjacent rooms; the right hand end of Figure 1 illustrating my improved means as employed in connection withdouble doors, while the left hand end of Figure 1 illustrates a modification of the invention as disclosed in the first four figures of the employed in connection'with single doors.

In the embodiment shown at the right, in Figure 1 and in Figure 2, the compartment or bath room is shown provided with double I doors at each entrance, to-wit what may be termed an outer door 10 hinged to swing outwardly as indicated in dotted lines and 11 and 10, however, can only be obtained o when my locking means has been actuated by an individual occupying the bath room or toilet as the case may be.

The object of my invention is to provide mechanism which can only be operated from within the bath room or toilet and whereby the doors leading from the room or apartment on the opposite side of the bath room or toilet and therefore not occupied or belonging to the individual in the toilet or bath room will be locked from the bath room or toilet side so as to prevent entrance from the adjoining room or apartment; while the inner door leading from the room or apartment occupied or elonging to the user of the bath may be locked from the inside and the corresponding outer door, however, held in such position as to prevent the accidental closing or latching of same and thereby. prevent the individual leaving the bath or toilet.

'To carryout this object, I provide oscilvlatably mounted means preferably illustrated in the nature of two rods 12 and 13; arranged in alignment and slidably secured in a tubular member 14 which latter may be provided with any suitable means, as for example the fastening screws or bolts 15, 15

ing position. The tubular member 14, at an intermediate point, is provided with a suitable outwardly disposed handle or exten-' sion 17 whereby the tubular member 14 with the rods may be oscillated. The tubular member 14 is secured-to the wall 18 of the compartment, namely the/wall disposed at right angles to the doors, by means of suit- ,able clips or brackets 19, 19 of such construction as will permit free oscillation of the tubular member. The wall 18, at a point above the tubular member and in alignment with the handle 17 is provided with a suitable spring clip or latch member 20 which is shown in the nature of two corresponding spring members or prongs arranged in close s aced relation and bent to receive the handle 1 therebetween and provide gripping relation therewith when the handle has been forced upwardly therebetween as shown in Figure 2.

The user doors 11 of the bath compartment a each provided with a latch member or dog 21 disposed through a suitable opening in the inner doors and pivotally secured therein in any convenient manner as illustrated at 22 so as to oscillate vertically. Each latch member 21 has the end, which is disposed between the correlated inner door 11 and outer door 10, formed in the nature of a downwardly disposed hook as at 23, while the other er (1 exten is through and protrudes on the compartment-side of the inner door 11. These latchmembers 21 are so formed or of such length and so pivoted that the ends protruding into the bath or toilet compartment are of greater weight'than the hook-ends thereof in order that the outer ends will drop downwardly, through the action of gravity, and therefore maintain the hook-end 23 normally in raised and unlatched position.

The outer doors 10 are each provided, at a. point in proximity to the latch members 21,

' wlth a lug,or bracket 24 formed to provide an upwardly disposed hook in spaced relation with the door 10 adapted to have the hook-end 23 of the latch member 21 pass over the top and engage the free end or hook of the bracket 24, thereby providing lockin relation between the correlated inner an outer doors as indicated in Figure 3.

The composite locking rods 121314, by reason of the forwardly presented curved ends 16,- will automatically swing downwardly so as to bring the curved ends 16 a parallel with the wall 18 in the manner indicated in dotted lines in Figure 2, when the handle 17 has been pulled from between or free of the spring clip 20. W'ith the curved ends 16, 16 out of supporting relation with the latch-members 21, the latter will'be allowed to tilt through the action of gravity, causing the hook-ends 23 to move upwardly .and out. of latching engagement with the lugs or brackets 24; a latching engagement normally being impossible, whileat the same time permitting all of the doors to becompletely closed.

The individual using the bath compartment upon entering leaves the outer door 10 leading from his apartment or room slightly ajar while his inner door 11 may be completely closed; he then grasps handle 17 and swings it upwardly between the spring clip 20. The upward movement of the handle oscillates the composite rod into the position shown in full lines in Figure 2, namely with the curved ends 16 brought upward beneath the protruding ends of the latch members 21, causing the latter to tilt on their respective pivotal points 22, and inducing the hookends 23 thereof to engage with the brackets or lugs 24 on the inner sides of the outer doors 10. In the case of the doors leading from the. adjacent apartment, where both .doors are in complete closed position, it is apparent that the hook-end 23 will engage 'rearwardly of the hook or bracket 24 and lock the outer door 10, leading from said adjacent apartment, to its respective inner door and preventing access to the bath from said apartment. On the other hand, by leaving his own outer door 10 partially open, the tilting of the latch member 21 on his inner door 11 will. move the hook-end 23 thereof downwardly where it will be in the path of and abut against the lug or bracket 24 on his outerdoor 10, in the event that his outer door is swung toward closing position, and thus prevent said outer door from being completely closed, accidentally or otherwise. and therefore from becoming latched or locked from the room-side and prevent his egress from the bath compartment. 011 the other hand, the upwardly swung curved end 16 of the locking rod will prevent his inner door 11 being opened from the room-side.

The locking rod has been illustrated and described as consisting of the two rods 12,

13 and the tubular member 14, in order to provide a longitudinally extensible rod which may be, readily adjusted to compartmerely single doors are employed; that is to say, a single door leading to the compartment from the rooms or apartments on adjacent sides thereof as very clearly shown to the left in Figure 1. These doors are adapted to swing into the compartment or toilet in a manner similar to the inner doors 1 11 at the right hand end of Figure 1 where the double door construction previously described is shown. In this form of the invention, the outer or room side of each door is provided with a bolt 26 slidably held in a 20 place by suitable brackets 27, 27 Each latch member or bolt is provided with a knob or grasp as at 28 see Figures 1 and 6, whereby the bolt may be moved to locking position from the room side of the door.

5 The doors 25, like the inner doors 11 of the double door construction, are each provided with a pivoted pawl or latch member 21 which may be substantially identical with the latch members heretofore described, ex-

'cept that the latch members 21 in this construction need not be provided with a hookend, with the bath or toilet side of the latch member protruding a distance sufficient. to be engaged on the under side thereof by the curved ends 16 of the locking rod which preferably consists of the members 12, 13 and 14 as previously described; the tubular member 14 being providedqvith the handle 17 which is adapted to be snapped between the spring clip 20 when the locking rod has been oscillated upwardly so as to bring the two bent or curved ends upwardly away from the adjacent wall.

Each latch or bolt 26 at a point adjacentto one end, namely the end farthest removed from the free edge of the door, is provided with a notch as at 29. This notch 29 is adapted to receive the short arm of the latch member 21', when said bolt 26 has been 0 withdrawn from bolting position, and thus prevent the bolt 26 being inadvertently moved into locking position on the door leading from the apartment or room of the individual in the compartment or bath room. On the other hand, the position of latch member 21, relative to the end of bolt 26,

is such, that when the bolt 26 has been moved into'locking position and the latch member 21 ,has been lifted by the ends of the locking rod, the short arm of latch member 21 will be in abutting relation with the rear end of the bolt 26 and prevent its withdrawal. This last mentioned condition is the one which would take place on the door leading from the opposite apartment or room and the latch member '21 will remain in abutting relation with the rear end of the bolt 26 as long as the-composite locking rod is in its upwardly oscillated position with the curved ends 16 thereof holding the inner ends of the latch member 21 upwardly.

The constructions shown and described I believe are the simplest adaptations of my invention; permitting easy operation as well as the ready adjustment of the device to. compartments of varying sizefelative to the doors leading from adjacent rooms; and I have described the same in terms employed merely as terms of description and not as terms of limitation, as structuralmodifications are possible and may be made without,

however, departing from the spirit of my invention.
